Abstract (en)
[origin: EP0232902A2] A multilayer compression-molded article produced by compression-molding a composite plastic material. The composite plastic material comprises a first synthetic resin and a second synthetic resin in which the first synthetic resin surrounds substantially the entire second synthetic resin. The compression-molded article comprises a first resin layer (34) molded from the first synthetic resin and a second resin layer (36) molded from the second synthetic resin in which the first resin layer (34) surrounds substantially the entire second resin layer (36). The composite plastic material is obtained by an extrusion apparatus which intermittently extrudes the second synthetic resin via a subsidiary extrusion flow passage (84) into a main extrusion flow passage (64) in which the first synthetic resin flows.
